How can I sum original and remaining time estimates upward to parent issues?

[Andy Smith]

We are using original time field on sub tasks to estimate effort and remaining time field to track progress. We would like to aggregate these up to the Stories and Tasks and, from there aggregate up to Epics. 

I have trawled for answers to something that I seem to remember was a standard check box option in the past but have come up with dead ends. 

Has anyone managed to use automation to do this and if so, in detail with pictures, could you please, please tell me how?

Sorry, it's unclear what you're trying to do here, so I can not really give you a clear answer.

As a starting point though, the searches return issues based on criteria, so you can easily run a search for "Issues in project A or Project B" and then include the custom fields in the output.  And you could also add "and custom field = X, Y or Z" to narrow it down more.  The issue navigator allows you to sort by any of the columns.

So, it is possible to do some comparisons, but I think you are looking for more than that.

I'm looking for the way to make filter which show only issues with different amount of attachments between root and escalated project.

Filters are for finding issues, not doing calculations. You'll need to run two filters and compare them
